CHARGING SYSTEM DATA LIST / ACTIVE TEST

  1. DATA LIST

    Tip:

    Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

    Note:

    In the table below, the values listed under Normal Condition are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

    1. Warm up the engine.

    2. Turn the ignition switch off.

    3. Connect the GTS to the DLC3.

    4. Turn the ignition switch to ON.

    5. Turn the GTS on.

    6. Enter the following menus: Powertrain / Engine and ECT / Data List.

    7. According to the display on the GTS, read the Data List.

      Powertrain > Engine and ECT > Data List

      Range

      Normal Condition

      Diagnostic Note

      Battery Voltage

      Battery voltage

      Min.: 0.000 V

      Max.: 65.535 V

      11 to 14 V (Idling)

      If the result is not as specified, abnormal battery voltage is suspected.

      Min.: 0.000 V

      Max.: 79.998 V

      13.5 to 14.4 V

      (After engine start (Varies with battery temperature or driving conditions))

      If the result is not as specified, a malfunction of the charging system is suspected.

      Alt Vol - Active Test

      Request voltage when regulator under forced activation

      Min.: 0.000 V

      Max.: 79.998 V

      10.6 to 16 V

      (After engine start (Request instruction voltage value))

      If the result is not as specified, a malfunction of the charging system is suspected.

      Tip:

      Normal Condition: If no idling conditions are specified, the shift lever should be in N (Neutral) or P, and the A/C switch and all accessory switches should be off.

  2. ACTIVE TEST

    Tip:

    Using the GTS to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Active Test.

    5. According to the display on the GTS, perform the Active Test.

      Powertrain > Engine and ECT > Active Test

      Tester Display

      Measurement Item

      Control Range

      Diagnostic Note

      Control the Voltage of Alternator
